Sonego is a picturesque hamlet at 425m above sea level, situated on a fertile and enchanting open valley on the left hand side of the Carron River, at the feet of Mount Pizzoc. It is surrounded by localities such as the Piani (835m a.s.l.) and Col Ronc (736m a.s.l.) to the North and by Mount Castello (465m a.s.l.) and Col Meneguz (475m a.s.l.) to the South.

In the old area of the hamlet one can see several antique terraced houses (in order to save space) built with exposed stones. One building on the square has this inscription on the internal wall: "7th June Year MDCCLXXXIII (1783) Dom. Michiel". The houses are connected by characteristic porticoes and the typical "matonà" (a pavement made with stones). The more recent area of the hamlet expanded to the South near the new church, while the ancient church, found in the old area, is now a private dwelling.

Fratte

Fratte is a hamlet on the left hand side of the Carron River, close to Cappella Maggiore. The name Fratte reminds us of the defensive role this access area leading to Fregona had in the ancient past (Fratte - from Latin - inhabited area near a fortress). The small Church of Saint Giusto is the fitting centre of the locality. The chapel is found on the little square opposite the mansion ex Altan-Pancetti, which has been recently rebuilt following its elegant original architecture.

The notable historical and artistic heritage of the two buildings is proved by a Latin inscription on the façade of the villa - "vetus sacellus prope cast. Charoni D. Justo dicatum" - confirming the existence, 100m from the Castle of Carron, of an old oratory dedicated to Saint Giusto. It referred most certainly to the "Chapel S. Justi", mentioned together with "Chapel S. Martini", "Castro (Castle) of Carron", and "Curtem (Court) de Fregona", all under the jurisdiction of the Bishop Count of Belluno.

Osigo

Osigo is the most populated hamlet of Fregona. It is situated on a flood plane at the feet of two hills called respectively Pravinera (647 a.s.l.) and Saint Daniel (451 a.s.l.), with River Bordon to the West and River Vizza to the East.

Osigo's church is a most interesting historical and artistic testimony, where a Francesco Da Milano's masterpiece, together with other precious works dating back from the end of the 16th to the 18th century are hosted. Outside the church, direction North-East, one can admire the bell tower with its "bifore" (mullioned windows) and its spiking pinnacle. The bell-tower resembles the one situated in Serravalle, which again follows the model of the notable Saint Mark's in Venice.

Osigo is surrounded by hills covered by vineyards of Prosecco, Boschera and Verdiso, vine varieties used for the production of "Torchiato", a typical "Passito wine" (made from dried grapes) of Fregona.

In a locality called "Col", South of the hamlet of "Luca", an antique wine press is on show. It was used to press the dried grapes (raisins) to make Torchiato.

In Osigo there's a new building specifically equipped for the drying of the Torchiato grapes.

Piai

Walking North, at the left hand side of Fregona's Town Hall, one reaches the old hamlet of Piai, where the remains of an ancient castle belonging to the Da Camino noble family can be visited.

Most probably, Piai had its origins because of the existence of the castle, as peasants gradually built their dwellings close to the castle, where they could find easy refuge and protection in case of invasions.

Zangiacomi wrote something interesting concerning the castle:

"Those ruins call to our imagination that rough and belligerent age, when the din of spears broken against iron shields and the noise of crossed swords in mortal duels could be heard".

Ciser

The small hamlet of Ciser is located on a gentle slope North-East of Piai and East of the ridge starting from Serravalle, at the feet of the now dismantled cableway, used in the past by the cement producing company called Italcementi to transport the stones extracted from the nearby mountain.

Of notable interest is the chapel in the little square next to the fountain.

An alleyway, called "The way of the waters", goes through the old stone houses and, with its magnificent landscapes, connects Piadera (a locality North-East of Vittorio Veneto) with the hamlet of Osigo.

Breda

Breda is a tiny hamlet West of Piai and South of Mount Castello along the hills leading directly to Vittorio Veneto. In Breda one can visit the Caglieron Caves, one of the most admired and visited natural spots around Treviso.

In Breda, just outside the caves, one can see two picturesque mills, dating back to the 16th century, a testimony to the milling work of the past, which used the natural availability of water in the area. One of the mills is now a restaurant and one a B&B.
